Product Description:

The MSK101E-0202-FN-M1-BG2-NNNN is a synchronous servo motor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. It converts drive current into precise rotary motion for industrial automation axes that need high accuracy and repeatability, including gantry stages, packaging stations, and metal-cutting spindles. When connected to an IndraDrive controller, its built-in encoder supplies feedback for closed-loop speed, torque, and position control. This allows the motor to support rapid acceleration, controlled deceleration, and stable positioning under changing load conditions.

The FN cooling designation indicates liquid cooling, which removes heat from the motor and supports continuous torque at high current density. An electrically released holding brake provides 70 Nm of static torque for axis retention when power is off, and the housing has an IP65 rating for use in wet processing cells. Feedback is transmitted through a Hiperface interface, and the optical encoder resolves rotor position over 128 signal periods for smooth commutation. Mechanical power is transferred through a plain shaft, which supports direct coupling to gearboxes without a keyed shaft connection. The motor uses a B-side power connector, and its size 101 housing with motor length E fits high-torque axes where cable routing space is limited.

The optical encoder also provides multi-turn absolute feedback, so full revolutions remain tracked and homing after power loss is not required. The motor is intended for ambient temperatures from 0 to 40 °C, which matches typical industrial cabinet and machine conditions. Its insulation system is classified as 155, allowing the windings to tolerate elevated temperatures during overload periods. These values describe operating limits for the motor and distinguish ambient temperature capability from internal insulation temperature tolerance.
